What do you do when the lights go out?

Abstract

Most facilities have good procedures for conducting routine switching and maintenance. However, what are the procedures for an unplanned breaker trip or equipment failure? Who do you call? How do you lockout? Where do you ground? How do you assess the damage? How do you restart? These are all items that need to be thought about ahead of time so as not to waste a lot of time and create potential safety issues when they happen.
